    OK. So, on advice, I thought I'd build this up motor by motor. I connected one of the outboard motors power leads to a single battery and ensured that this had the red positive connected in the the ESC cable. I then tested this set up and, as we'd expect, the motor primed and functioned correctly. I then connected the motor next to it, one of the inboard fans, connecting the power leads from this and the first fan to the single battery, ensured the red positive was disconnected from this second ESC and guess what, only the inboard fan worked. Clearly the power from the first ESC (outboard fan) was making it to the Rx but no signal was getting back?

    I've been at this thing again today. The manual makes no sense to me re slaving channels. The example given seems to suggest having the throttle channel as the master and the throttle channel as the slave which to me makes no sense at all. Appreciating this is just the example I've slaved Aux 2 to the Throttle and it still doesn't work! Anyone want to buy a partly completed Vulcan!!!! Seriously. I've swapped the Rx for a slightly larger one and one that offered another channel. I've provided the Rx with a separate power supply. I've tried to slave the Aux 2 to the throttle as best I can given the instructions don't make a lot of sense to me. Still I only get 2 motors running. I've also used my cheap and cheerful (and only) servo tester to see if I get anything from the speed controllers which I do, even if the signal is very broken up, on all four. The first diagram re the wiring is the correct one - for some reason I can't delete the original which showed the batteries connected to the wrong speed controllers.

    Right everyone. I'm reliably informed that I need to 'stop messing about with my plane and get ready to go out' so, I'll sign off for now. Thank you everyone for the input. Lots to consider/try etc. May I wish you all a Happy New Year and maybe, just maybe, 2023 will finally see this Vulcan take to the skies and I won't have to satisfy myself with a trip to Wellsbourne airfield to see a real one (mind you, mine could taxi on two EDF's just like that one does 🙂 ) T

    Great memory Nik, I can barely remember what I did this morning let alone what someone posted many years ago. Good point re the Rx power. Pointless trying to get redundancy this way.

    So to Andy Joyce's point it may be that I need to provide some additional power to the Rx?

    On this diagram is it right that only the white data wire is connected from each speed controller?
  7. TonyS
    No such thing as silly at this stage. Got to be worth a try. I have had the outward EDFs working but who knows....
  8. TonyS
    Latest attempt.....
  9. TonyS
    So I've just connected the negatives and still nothing?
  10. TonyS
    Andy, it's via the power wire from the ESC

    Thanks Frank, I have put a signal booster in the circuit between the 4 in 1 and the Rx. The retracts work well - and they are quite chunky, so I'd be surprised if there was insufficient signal to power 4 ESCs but then, what do I know.... I've just connected all the negative leads from the batteries however I still only get the two inboard fans powering up. I'm using a Spectrum AR500 Rx which is small but there are spare channels. I'm not sure how to slave a separate channel to the throttle though?
  12. TonyS
    There's no sep. BEC supply -
  13. TonyS
    That may well be the issue........ The negatives aren't interconnected!
  14. TonyS
    Yes, a mistype. Oops!
  15. TonyS
    Yes, apologies, the power is what's disconnected.
